Unlocking Energy Savings: The Truth About Smart Plugs (2024)

Smart plugs are becoming extremely popular as they are a great way to turn your appliances smart. Many homeowners use smart plugs as the first step to creating smart homes. Due to this high demand, many homeowners wonder - do smart plugs save energy?

A smart plug has several high-quality functions, and some of them provide helpful ways to conserve energy and save on your utility bills. Here is everything you need to know about how smart plugs save energy.

What Is A Smart Plug And How Does It Work?

Before discussing if smart plugs save energy, it is important to understand the functionality of a smart plug. So what is a smart plug? A smart plug is a power receptacle that installs into a conventional electrical socket. This smart plug also integrates into a smart home network. You can control whatever device you plug into the smart plug from an app on your smartphone or tablet.

You can also control the device through a virtual home assistant device. Many homeowners use a smart plug to convert ordinary devices into smart devices.

For access to a large number of features and good reliability, it is recommended that you connect your smart plugs to Wi-Fi. You can connect a smart plug to Wi-Fi directly or use a bridge that plugs the device into your router. Here are some important features of smart plugs:

  • Some smart plugs are compatible with virtual home assistant devices; therefore, you can speak directly to your smart plug instead of using an app.
  • Smart plugs connect to the Wi-Fi, which allows you to control your plugged-in devices remotely through a smartphone or tablet.
  • Some smart plugs have voice control options that make them compatible with Google Assistant and Siri on your smartphone.
  • You can use your smartphone to set timers. These timers will automatically turn appliances on or off at the scheduled time.
  • With a smart plug, you can track the energy consumption of your appliances and fixtures. The data tells you how much the appliances are costing you in real time.
  • If you don’t want to control your smart plug with your smartphone, some plugs come with a handheld remote with a simple on/off feature button.
  • Smart plugs provide several safety features. If you forget to turn your appliances off, you can use the schedule feature to set specific operational times for your devices. If you are away from home, you can schedule your lights to turn on at night to keep away any intruders.
  • Specialised outdoor smart plugs allow you to operate and schedule outdoor lighting fixtures such as holiday lights. These plugs are manufactured to withstand several outdoor weather elements. Check outdoor smart plugs for an IP rating to ensure they are fit for outdoor use.
  • Many conventional devices go into standby mode instead of turning off completely. Devices on standby still consume energy and raise your energy costs. Smart plugs solve this problem by reducing latent energy consumption. Smart plugs do not act as standby saver plugs, instead, they turn the devices off completely instead of letting them go into standby mode. This allows them to act as energy monitoring plugs.
  • Smart plug strips not only plug in multiple devices but also send you an alert if the power strip is overloaded. A smart plug strip also sends you an alert in the event of a safety hazard.
  • Does a plug use electricity when switched on? and does leaving switch on use electricity? Yes, any plug that is plugged into a socket that is switched on will use up electricity. So, does turning off switches save electricity? Yes, if you have regular plugs around your space, turn them off when they are not being used. However, a smart plug will automatically switch off when a device is going into standby. Smart plugs are therefore energy-saving plugs.

How Much Energy Do Smart Plugs Use?

To understand do smart plugs save energy, here are looking at how much energy a smart plug takes up. In most cases, a smart plug uses approximately 1 watt of energy when it is in standby mode. This wattage also depends on the type of connection it uses. Since a smart plug is connected to something else in your household, it is always active.

However, if you connect your smart plug to Wi-Fi, your plug will only use about 1 to 2 Watts maximum in a day. You can expect even lower energy consumption if you use Zigbee or Z-wave network for your smart plug instead of Wi-Fi. For these networks, the average energy consumption is between 0.3 to 0.6 watts.

Do Smart Plugs Save Energy?

So, do smart plugs save energy? Yes, they do. When used correctly, smart plugs can help you save energy and, ultimately, utility costs in the long run.

Some smart plugs also provide energy consumption data which you can use to make your household more energy efficient. Some of these energy statistics also let you know where you are spending the most money. You can look at this data and make changes accordingly to save money.

There are some smart plugs that let you input your energy supplier’s price. This feature allows you to get exact information on how much the plugged-in appliances are costing you. With features such as these, you can make better decisions when it comes to your household’s energy consumption. Keeping track of your energy consumption is just one way in which smart plugs help you save energy.

If you're wondering, do plugged in appliances use electricity? As mentioned before, a large portion of your electricity costs come from appliances on standby mode. Many appliances do not shut off completely when they are switched off manually. These devices go into standby mode and keep consuming energy. For example, how much energy does a TV use in standby? On average, and LCD consumes up to five watts while on standby and between 24-50 watts while you're watching. And does turning tv off at the wall save electricity? Yes, while it may not a big cut in your energy bill, it is sure to help. Such standby energy-consuming appliances include the TV, gaming console, and laptop chargers. These devices continuously use energy even when you are not using them.

Even though these devices are not fully operational, they still consume a significant portion of energy. The average UK household spends £55 a year on powering electrical devices on standby mode. This figure shows just how much money is spent on energy that is wasted. However, since these appliances power home entertainment systems, it is not practical to shut them off completely. You can solve this problem by using smart plugs.

Smart plugs work well with some of these appliances, and they can turn such appliances off completely instead of sending them into standby mode. A smart plug also provides access control over these devices, and you won’t have to touch electrical wiring or hard-to-reach places to shut these devices off.

Forgetting to turn appliances off is another way energy is wasted in a household. If you are prone to leaving your home with appliances still turned on, or if you are forgetful, you can greatly benefit from a smart plug. Plus, if you're wondering is it dangerous to leave a socket switched on? It is. Whether it's a clothing iron, coffee maker, or hair straightener, when you plug these devices into a smart plug, you don’t have to worry about leaving them on while you are away from home.

Smart plugs allow you to control your appliances remotely, and if you leave your home without turning the coffee makers on, you can simply use your smartphone to power off the appliance.

Some smart plugs also allow you to set up a sleep timer that powers off the appliances after a time period has passed. For example, if you think you forget to turn off your table lamps at night before going to bed, you can schedule a timer on your lamp with a smart plug. The smart timer plug will automatically shut off the lamp when you go to bed.

Some homeowners have energy tariffs that provide cheaper electricity at night rather than during the daytime. You can use a smart plug timer to turn on appliances during the evenings.

You can also set the timer to avoid turning on any high-energy-consuming appliances during peak electricity consumption hours. This ensures that you will keep your energy costs low in the long term, and you will also make a better impact on the environment.
